- Bonterra increased its reserve base in 2008 by 12.1 percent on a total proved (TP) basis and 14.4 percent on a proved plus probable (P+P) basis to total 24.1 million barrels of oil equivalent (boe) and 31.2 million boe, respectively, through a combination of improved operations, organic development and acquisitions.

- Reserves per share increased 13.0 percent to 1.83 boe per share at December 31, 2008 compared to 1.62 boe per unit in 2007 on a P+P basis.

- Average daily production in 2008 totaled 4,346 boe per day, an increase of three percent when compared with 2007 levels. Average daily production in the fourth quarter of 2008 totaled 4,587 boe per day, an increase of 6.8 percent when compared to the fourth quarter of 2007.

- Bonterra's low decline production is supported by its high-quality reserve base. The reserve life index (RLI) in 2008 increased to approximately 14.4 years on a TP basis and 18.7 years on a P+P basis versus the 2007 RLI of approximately 13.7 years on a TP basis and 17.4 years on a P+P basis.

- Bonterra continues to focus on the efficient development of its asset base. Finding and development (F&D) costs including future development costs in 2008 decreased from our three year averages and continue to be among the lowest in the industry. F&D costs including acquisitions in 2008 were $8.68 per boe on a TP basis and $7.48 per boe on a P+P basis compared with the previous three year average (2005-2007) of $14.27 per boe on a TP basis and $11.07 per boe on a P+P basis.

Certain financial and operating information included in this press release for the quarter and year ended December 31, 2008, such as production information, finding and development costs and net asset values are based on estimated unaudited financial results for the year and are subject to the same limitations as discussed under Forward Looking Statements set out below. These estimated amounts may change upon the completion of audited financial statements for the year ended December 31, 2008 and changes could be material. All reserve numbers provided above are Bonterra's interest before royalties.

It should not be assumed that the estimates of future net revenue presented in the above tables represent the fair market value of the reserves. There is no assurance that the forecast prices and costs assumptions will be attained and variances could be material.

Estimates of reserves and future net revenues for individual properties may not reflect the same confidence level as estimates of reserves and future net revenues for all properties due to the effects of aggregation.

Caution Regarding Engineering Terms:

Disclosure provided herein in respect of barrels of oil equivalent (boe) may be misleading, particularly if used in isolation. In accordance with NI 51-101, a boe conversion ration of 6 MCF to 1 barrel has been used in all cases in this disclosure. This boe conversion ratio is based on an energy equivalency conversion method primarily available at the burner tip and does not represent a value equivalency at the wellhead.
